A. a spectrophotometer is known to have 0.800% stray light reach the detector for all analyses due to poor light sealing. determine the true absorbance, apparent absorbance, and apparent transmittance for a sample with a true transmittance of 0.0811.
b. what amount of stray light produces an apparent absorbance of 1.995 with a true transmittance of 0.0100?
c. in the process of performing an analysis, you determine that you need to improve the precision by limiting the error in the absorbance to 0.7200. you attempt to achieve this by reducing the amount of stray light that reaches the detector. what is the maximum amount of stray light that can reach the detector that will limit the error in the absorbance to 0.7200 for a true absorbance of 1.1?
